Tam sim no, stainless hlau dab dej yog yuav luag txhua tsev neeg, indispensable chav ua noj tais diav, tab sis koj puas to taub lub ntsiab hlau ntsiab ntawm stainless hlau cov khoom thiab lawv cov dej num? Qhov tseeb, feem ntau cov neeg tsis paub ntau txog qhov no, yog li tus editor yuav qhia luv luv thiab nrov rau koj hnub no, Kuv vam tias koj tuaj yeem nkag siab tob txog lwm yam khoom siv hlau tsis zoo xws li cov dab dej stainless hlau tom qab nyeem ntawv.
Ua ntej, cov ntsiab lus hlau tseem ceeb muaj nyob hauv lub dab dej stainless hlau
Nyob rau hauv lub neej niaj hnub, peb feem ntau raug rau 201, 304 stainless hlau cov khoom, feem ntau muaj nickel (Ni), chromium (Cr) ob hlau ntsiab. Ntawm lawv, 304 stainless hlau qib: 0CR18NI9, uas cov ntsiab lus chromium yog 18 feem pua -19 feem pua, cov ntsiab lus nickel yog 8 feem pua -9 feem pua; 201 stainless hlau qib: 1Cr17Mn6Ni5N, uas cov ntsiab lus chromium yog 12 feem pua -13 feem pua, thiab cov ntsiab lus nickel yog 1 feem pua -1.5 feem pua. Yeej, cov ntsiab lus nickel txiav txim siab tus nqi ntawm stainless hlau dab dej.
Thib ob, lub luag haujlwm ntawm cov khoom hlau hauv stainless hlau dab dej
Lub luag haujlwm tseem ceeb ntawm npib tsib xee hauv cov khoom siv stainless hlau yog tias nws hloov cov qauv siv lead ua ntawm cov hlau, kom cov qauv siv lead ua hloov pauv ntawm lub cev ntawm peb sab (BCC) qauv mus rau lub ntsej muag-centered peb-dimensional (FCC) qauv, uas tuaj yeem txhim kho cov plasticity thiab toughness ntawm stainless hlau, thiab ua kom cov ductility ntawm stainless hlau raw cov ntaub ntawv zoo dua.
Qhov laj thawj tseem ceeb vim li cas chromium tau dhau los ua lub hauv paus tseem ceeb los txiav txim siab qhov kev ua tau zoo ntawm cov hlau tsis muaj steel yog tias tom qab ntxiv ntau dua 12 feem pua ntawm chromium rau hlau, nyias nyias tsis muaj xim, pob tshab thiab du oxide zaj duab xis (uas yog, zaj duab xis passivation) yuav raug tsim. nyob rau saum npoo ntawm cov hlau, thiab tsim cov yeeb yaj kiab no ua rau cov oxidation ntawm cov hlau tsis zoo thiab ua rau cov khoom siv hlau tsis muaj xeb zoo dua.
